A. Bravo et al., SOME ASPECTS OF THE PHOTOCATALYTIC OXIDATION OF AMMONIUM ION BY TITANIUM-DIOXIDE, Journal of chemical research. Synopses, (9), 1993, pp. 376-377
The oxidation of NH4+ to NO3- by near-UV illumination of TiO2 is found
to follow Langmuir-Hinshelwood kinetics; the effects of pH and compet
itive adsorption have been studied.
